Martensite’s Logistic Paradigm [PDF]

Materials Research, 2021
Abstract This work introduces a deterministic approach to the martensite transformation curve. Martensite is a nucleation-controlled transformation that has two characteristics: autocatalysis and auto-accommodation. Only a small number of martensite units initially form owing to primary nucleation.

Building Hierarchical Martensite [PDF]

Advanced Functional Materials, 2020
AbstractMartensitic materials show a complex, hierarchical microstructure containing structural domains separated by various types of twin boundaries. Several concepts exist to describe this microstructure on each length scale, however, there is no comprehensive approach bridging the whole range from the nano‐ up to the macroscopic scale.

Lattice deformations at martensite-martensite interfaces in Ni-Al [PDF]

Le Journal de Physique IV, 2001
The atomic configurations at macrotwin interfaces between microtwinned martensite plates in $Ni_{65}Al_{35}$ material are investigated using high resolution transmission electron microscopy (HRTEM). The observed structures are interpreted in view of possible formation mechanisms of these interfaces.

Comparison of the fracture resistance of the teeth prepared with ProTaper Universal, ProTaper Next, and ProTaper Gold rotary files

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1421-1425, December 2022., 2022
Abstract Objectives Root canal preparation can lead to cracks on the roots by creating stresses on the root canal walls, which decreases the fracture resistance of the tooth. The present study compared the fracture resistance of the teeth prepared by the ProTaper Universal (PTU), ProTaper Next (PTN), and ProTaper Gold (PTG) rotary file systems ...

Effect of Chromium and Molybdenum Increment on the Crystal Structure, Nanoindentation, and Corrosion Properties of Cobalt‐Based Alloys

physica status solidi (a), Volume 219, Issue 23, December 2022., 2022
This study deals with the microstructural, nanoindentation and corrosion properties of the cobalt–chromium–molybdenum alloy system. Hardness increases linearly as a function of chromium, while reduced modulus shows maximum for Co30Cr5Mo and Co25Cr10Mo, respectively.

A Near‐Process 2D Heat‐Transfer Model for Continuous Slab Casting of Steel

steel research international, Volume 93, Issue 12, December 2022., 2022
The simulation results for the selected case of studies, obtained with m2CAST, show reasonable accordance with industrially measured surface temperatures by thermocouples and pyrometers installed at a continuous slab caster. m2CAST is a promising tool for optimizing the secondary cooling parameters and adjusting soft reduction settings to enhance the ...

The Features of Martensitic Transformation in 12% Chromium Ferritic–Martensitic Steels [PDF]

Materials, 2021
An anomaly in martensitic transformation (the effect of martensitic two-peak splitting in the temperature-dependent thermal expansion coefficient) in complex alloyed 12% chromium steels Fe-12%Cr-Ni-Mo-W-Nb-V-B (ChS-139), Fe-12%Cr-Mo-W-Si-Nb-V (EP-823) and Fe-12%Cr-2%W-V-Ta-B (EK-181) was investigated in this study.

Influence of Aluminum on the Wear Properties of High‐Carbon Metastable Austenitic Steels

steel research international, Volume 94, Issue 1, January 2023., 2023
The two‐body wear properties of high‐carbon metastable austenitic steels (MAS) are investigated and compared to conventional wear‐resistant steels. MAS exhibit wear resistances up to five times greater than conventional wear‐resistant steels. The effect of aluminum addition on the wear properties of such MAS is investigated and discussed in terms of ...

On the mechanism of martensite nucleation [PDF]

Acta Metallurgica, 1989
Abstract The martensitic transformation in the following two model systems, Fe-30 at.% Ni and In-5.25 at.% Cd, was studied by X-ray diffraction and metallography in order to answer the following question: does the nucleation of martensites occur by a soft mode mechanism or by classical heterogeneous nucleation?
